export JAVA_OPTS=”-Xrs -Xms128M -Xmx256M -Dsun.rmi.dgc.client.gcInterval=300000 -Dsun.rmi.dgc.server.gcInterval=360000 -Djava.net.preferIPv4Stack=true -XX:+ExplicitGCInvokesConcurrent -XX:+UseConcMarkSweepGC -Xverify:none”

Assuming red5 was installed in /opt/red5/dist admin will often need to restart it or check if it’s running.

Make sure Red5 restarts: restart.sh

#!/bin/bash
#Restart the process
#First see if running
PID=`ps -eo ‘tty pid args’ | grep ‘red5′ | grep -v grep | grep -v restart | tr -s ‘ ‘ | cut -f2 -d ‘ ‘`
cd /opt/red5/dist
if [ -z "$PID" ]
then
#not running
echo “Red5 was not running at `date`” >> /opt/red5/dist/run-restart.log
else
echo “Red5: $PID”
#shutdown
/opt/red5/dist/red5-shutdown.sh
sleep 6
#make sure
kill $PID >> null
sleep 2
fi
#start
/opt/red5/dist/red5.sh >> /opt/red5/dist/red5.log &
echo “On request restarted Red5 at `date`” >> /opt/red5/dist/run-restart.log

Mare sure Red5 process is running, if not start it: running.sh

#!/bin/bash
#set environment
PID=`ps -eo ‘tty pid args’ | grep ‘red5′ | grep -v grep | grep -v running | tr -s ‘ ‘ | cut -f2 -d ‘ ‘`
if [ -z "$PID" ]
then
#Restart the process
cd /opt/red5/dist
/opt/red5/dist/red5.sh >> /opt/red5/dist/red5.log &
echo “Restarted Red5 at `date`” >> /opt/red5/dist/run-restart.log
else
#do nothing
echo “Red5 is already running with PID=$PID at `date`” >> /opt/red5/dist/run-checked.log
fi

Run 2 rtmp servers at same time and allow applications to connect on both simultaneously.

First install Wowza Media Server. Update version if necessary.

cd /root/tmp
wget http://www.wowzamedia.com/downloads/WowzaMediaServer-2-0-0/WowzaMediaServer-2.0.0.rpm.bin
chmod a+x WowzaMediaServer-2.0.0.rpm.bin
./WowzaMediaServer-2.0.0.rpm.bin

Then fill your Wowza Media Server license ( a free developer license for 10 connections can be used for testing):

cd /usr/local/WowzaMediaServer/bin
./startup.sh

Change rtmp port in /usr/local/WowzaMediaServer-2.0.0/conf/VHost.xml from 1935 to some other port not in use (i.e. 1936):

<Root>
<VHost>
<HostPortList>
<HostPort>
<ProcessorCount>4</ProcessorCount>
<IpAddress>*</IpAddress>
<!– Separate multiple ports with commas –>
<!– 80: HTTP, RTMPT –>
<!– 554: RTSP –>
<Port>1936</Port>

Run Wowza in background. You can also add this to /etc/rc.d/rc.local to have it running on each server restart:

cd /usr/local/WowzaMediaServer/bin
./startup.sh > start.log &

Now you’ll be able to access wowza rtmp applications with rtmp://your-server:1936/your-wowza-application while red5 applications will be accessible the old way with  rtmp://your-server/your-red5-application .

An example of 2 rtmp servers running on same linux server is the VideoWhisper Webcam Video Recorder.

This should install ffmpeg, mplayer, mencoder, flvtool2, yamdi, x264, theora, mp3lame, vorbis, ogg, faac, faad2, xvid . These tools will enable on your server:

  • video conversion
  • thumbnail generation
  • FLV meta injection (flvtool2, yamdi)
  • extra codecs (x264, theora, mp3lame, vorbis, ogg, faac, faad2, xvid)

This is functional and we update it each time we configure a new server.
Installation is done using the “root” account.

Attention: If you copy and paste commands below, make sure “-” are not converted to “.”.  If these get converted, edit “.” back to “-”. Some options use 2 * “-”.

For other linux flavors (i.e. Centos) see this comprehensive tutorial Install Red5 and JDK on Centos.

This installation was done from windows so we used  WinSCP and PuTTy (free software)  and was inspired from online tutorials.
This installation was done fluently: if you go to other folders and do other tasks during the installation make sure you return to the right folder before resuming.

First installed required packages one by one:
apt-get install subversion
apt-get install java-package
apt-get install sun-java6-jdk
apt-get install ant

Used arrows to browse to the Ok and confirm on jdk installation dialogs.

Verified installed java version:
java -version

Downloaded latest Red5:
mkdir -p ~/svn/red5
cd ~/svn/red5
svn co http://red5.googlecode.com/svn/java/server/trunk red5

Build Red5 with Ant:
export JAVA_HOME=/usr/lib/jvm/java-6-sun/
export ANT_HOME=/usr/share/ant/
cd ~/svn/red5/red5
/usr/share/ant/bin/ant

Installed Red5:
mkdir /usr/share/red5
cp -R dist/* /usr/share/red5/
cd /usr/share/red5
chmod 755 red5.sh
chmod 755 red5-shutdown.sh

Started Red5:
./red5.sh > start.log &

Verified opened ports:
netstat -ant

To install a new rtmp application you need to:

  1. Copy application to /usr/share/red5/webapps (i.e. /usr/share/red5/webapps/videowhisper as explained on VideoWhisper RTMP Applications)
  2. Shutdown red5
    cd /usr/share/red5
    ./red5-shutdown.sh
  3. Restart red5
    ./red5.sh

An alternative to doing the red5 installation yourself would be to order red5 installation .

If you don’t have the time and experience to run your own server or vps, you should use managed red5 hosting .

Live Broadcast

Some of the improvements:

  • advanced webcam settings (change realtime resolution, framerate, audio rate)
  • fullscreen button for video watching interface
  • fullscreen on click for embedded plain video stream interface
  • generate updated jpg snapshots for each live stream
  • timers (displayed on each interface depending on settings) can be used to control access, integrate in pay per view systems
  • multiple new options and parameters passed from script side

Also some RTMP application improvements should be mentioned like external player support and live video archiving as FLV for the Red5 application.

Upgrades are available for download on VideoWhisper.com and do not involve any costs for free or paid licenses.

First edition available with the upgrade is the PHP edition. The rest should follow shortly.

]]> http://www.videochat-scripts.com/live-streaming-v2-by-videowhisper/feed/ 0 Use JW Player to play VideoWhisper application streams http://www.videochat-scripts.com/use-jw-player-to-play-videowhisper-application-streams/ http://www.videochat-scripts.com/use-jw-player-to-play-videowhisper-application-streams/#comments Fri, 28 Aug 2009 01:35:12 +0000 VideoChat Scripts http://www.videochat-scripts.com/?p=109 With the latest VideoWhisper rtmp applications versions, webmasters can enable external player support (both for FMIS and Red5).  This can be enabled from  RTMP Application Settings.

You need to have allowPlayers=true for FMIS or acceptPlayers=true for Red5 . These settings are turned on by default.

This will allow playing a stream published by a VideoWhisper flash application like Live Streaming with an external player like JW Player.

Demo:

Publish a stream from Live Streaming Demo (i.e. Studio1) and then view it on JW Player. Update channel name in link if you’re using a different one.

Here is the code to embed JW Player:

<?
include(“settings.php”);
$stream=$_GET['n'];
?>
<object id=”player” classid=”clsid:D27CDB6E-AE6D-11cf-96B8-444553540000″ name=”player” width=”328″ height=”260″>
<param name=”movie” value=”player.swf” />
<param name=”allowfullscreen” value=”true” />
<param name=”allowscriptaccess” value=”always” />
<param name=”flashvars” value=”file=<?=urlencode($stream)?>.flv&streamer=<?=urlencode($rtmp_server)?>&autostart=true” />
<object type=”application/x-shockwave-flash” data=”player.swf” width=”328″ height=”260″>
<param name=”movie” value=”player.swf” />
<param name=”allowfullscreen” value=”true” />
<param name=”allowscriptaccess” value=”always” />
<param name=”flashvars” value=”file=<?=urlencode($stream)?>.flv&streamer=<?=urlencode($rtmp_server)?>&autostart=true” />
<p><a href=”http://get.adobe.com/flashplayer”>Get Flash</a> to see this player.</p>
</object>
</object>

Also this code could be used for playing a Studio1 stream broadcaster with VideoWhisper Live Streaming. Make sure you have swobject.js and player-viral.swf in that folder.

<script type='text/javascript' src='swfobject.js'></script>

<div id='mediaspace'>This text will be replaced</div>

<script type='text/javascript'>
  var so = new SWFObject('player-viral.swf','mpl','320','320','9');
  so.addParam('allowfullscreen','true');
  so.addParam('allowscriptaccess','always');
  so.addParam('wmode','opaque');
  so.addVariable('file','Studio1.flv');
  so.addVariable('volume','5');
  so.addVariable('streamer','rtmp://your-rtmp-server/videowhisper');
  so.addVariable('autostart','true');
  so.addVariable('quality','false');
  so.write('mediaspace');
</script>
